37961dbd2d Auto merge of #55959 - matthewjasper:remove-end-region, r=nikomatsakis 
Cleanup from lexical MIR borrowck removal

Lexical MIR borrowck was removed months ago now, and `EndRegion`s are no longer used for MIRI verification.

* Remove `rustc::mir::StatementKind::EndRegion` and the `-Zemit_end_regions` flag
* Use `RegionVid` instead of `Region` in BorrowSet
* Rewrite drop generation to create fewer goto terminators.

Revert "appveyor: Use VS2017 for all our images"

This reverts commit 008e5dcbd5 (#55935)

We suspect this causes the spurious failure in https://github.com/rust-lang/rust/pull/55906#issuecomment-441365922 and https://github.com/rust-lang/rust/pull/55915#issuecomment-441377543.

4632cf2a2e Auto merge of #55935 - alexcrichton:vs2017, r=Mark-Simulacrum 
appveyor: Use VS2017 for all our images

This was [recommended by AppVeyor][1] to see if it has any impact on our
build times, hopefully on the beneficial side of things! This shouldn't
affect our binary compatibility for generated compilers like it would
normally do for Linux.

Rollup merge of #56154 - petrhosek:fuchsia-linker-args, r=alexcrichton 
Pass additional linker flags when targeting Fuchsia

This is a follow up to 8aa9267 which changed the driver to use lld
directly rather than invoking it through Clang. This change ensures
we pass all the necessary flags to lld.

Take 2 of #55971. Still ~wrong, but now with a comment! (and less of a surface) Unblocks #49219.
